Boeing has outsourced work to a number of Indian IT vendors in recent years; the layoffs are part of continuing efforts to cut 10,000 jobs

The Boeing Co. late last week issued 1,000 layoff notices to employees, many of them working in IT.

The company sent 60-day layoff notices to the workers, who are at risk of being laid off on April 23. Of those notices, about 800 went to employees of Boeing's Engineering, Operations & Technology unit; most of the people in that unit are in IT, according to Tim Healy, a company spokesman.

The company employs 158,500 people, including 18,000 in its engineering and technology group.

Healy said that between now and the layoff date, retirements and other forms of attrition could eliminate the need for some of the cuts, "although it's impossible to predict how often that could happen or how many employees will actually leave the company," he said.

This layoff plan is a continuation of efforts by Boeing to cut 10,000 jobs.

Boeing outsources some of its software development in India , but it was unclear whether that played a role in last week's announcement. Boeing has outsourced work to a number of Indian IT vendors in recent years.
